Came during lunch and it wasn't busy at all, maybe 2 people inside and nobody in the drive thru. I ordered carne asada fries with the guac and sour cream on the side. I never got my change and couldn't get anyone's attention in the drive thru so I had to go back thru and ask for my change. The lady didn't apologize or anything. When I got home I discovered they put the guac and sour cream on my carne asada fries when I asked them not to. The carne asada is so over cooked it's inedible. The only positive is they gave me a good amount of hot sauce. Super disappointed since I live right around the corner and it would be really convenient for me. Guess I'll just drive the extra mile and go to fiesta burrito.
